Frequently Asked Questions
Quick direct-answer guides about using this utility tool locally and securely.
How does the PDF Text Watermark tool work?
You can upload your PDF, enter custom watermark text, adjust opacity, size, color, and angle, then click watermark. The text is drawn directly onto every page of your PDF locally in your browser.
Can I choose the angle and transparency of the watermark text?
Yes, you can rotate the watermark text from -90 to +90 degrees (diagonal at 45 degrees is very common) and set custom opacity between 10% and 90% so the watermark does not block the document's main content.
Are my documents uploaded to any servers?
No, everything happens client-side. The file manipulation runs in your browser using local script buffers, guaranteeing your document's privacy.
